wx.request超时

network状态显示：

祭上代码：

wx.request({       url: url,       data: new Uint8Array(wx.getFileSystemManager().readFileSync(path)),       method: 'PUT',       dataType: 'json',       header: {           'content-type': ''       },       success: (res) => {           console.log('success', JSON.stringify(res));       },       fail: (res) => {           console.log('fail', JSON.stringify(res));       },       complete: (res) => {           console.log('complete', JSON.stringify(res));       }   });

console打印如下：

fail {“errMsg”:“request:fail timeout”}

complete {“errMsg”:“request:fail timeout”}
